A Proton account is now optional alongside public links. Signing in (password,
then a second-factor code and a mailbox password where the account has them;
a CAPTCHA gate is solved in the Android app) stores one session blob in the OS
credential store under `proton-account`, writing back every refreshed token
since refresh tokens are single-use. With an account, folders of the viewer's
own Drive — My Files, other devices, shared with me — can be added as shares
through the same `ShareClient` surface as a public link.
Watch history syncs through a `proton-stream` device in that Drive: one
`watch-history/<installation>.json` per installation, so no two devices ever
write the same file. Each sync reads the others and merges per episode, newer
`updated_at` wins, with a deterministic tie-break. It runs at launch, after
sign-in, whenever the player closes and every five minutes. A session that can
no longer refresh signs the app out instead of failing on every launch.
The CLI gains `login`, `logout`, `account`, `browse` and `sync`.
Also in this change:
- Android offline downloads no longer look stuck (B64): two transfer at once,
through a copy stream with no read-ahead, with a smoothed transfer rate.
- Choosing a metadata match by hand now enriches the title too, instead of
keeping the old match's episodes and artwork.
The catalog schema is unchanged.
- the streaming cache's budget (1-16 GiB) is chosen in Settings, shows
what it holds, and can be emptied; a lower budget evicts at once
- hardware decoding can be turned off for a driver that shows green
frames, from the next file
- both live in desktop.json rather than the playback prefs shared with
Android, whose bridge record would reset them on every save. A file
that will not parse is never overwritten
The up-next card shows the next episode's still with the seconds left
running round it, and the still itself plays it. The window opens at
the size and maximized state it closed at; position is left to the
window manager.
